The term lighting is not only limited to the natural sunlight but it also includes the artificial lighting like the light of lamp or the bulb. Light is powered through the energy system.

There are a variety of the types of light, depending on the distribution and the conversion of light. Firstly, task lighting, which is basically used while you are reading a book. This lighting basically concentrates on the small words of the book and the words become very prominent and clear. These lights are available in most of the table lamps and are also used as landscape lighting. Secondly, accent light that is used for the enhancement of the beauty of the pictures and the decoration pieces placed in a room. This light focuses on the fixtures and when it reflects back it makes the fixture look more beautiful in most of the restaurants and the clubs, for increasing the elegancy of the place through these lighting fixtures. Thirdly, normal lights that are used for the normal illumination of the place and these are usually in the form of the bulbs, tube lights and many other ceiling lights. Similarly, the track lighting is used for focusing on one place like in a Hollywood award show the track light is used to spot the actors and actresses.
